SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 389,248, dated September 11, 1888.

Application filed June 21, 1888.

To all whom it may concern;

Be it known that 1, JOHN ALEN Roonns, a citizen of the United States, residing at Hartsells, in the county of organ and State of Alabama, have invented new and useful Improvements in Sash-Balances, of which the following is a specification.

My invention relates to improvements in sash-balances; and it consists in a certain novel construction and combination of devices, fully set forth hereinafter in connection with the accompanying drawings, wherein- Figure l is a perspective view of a window in which the sashes are provided with the improved balance. Fig. 2 is a detail view of the sheave and the casting in which it is mounted. Fig. 3 is a similar view of the device for securing the free end of the cord and the adjustable stop.

Referring to the drawings by letter, A designates the lower and B the upper sash, and G designates a cord which is rigidly attached at one end to the top rail of the upper sash and passes over the sheave D, which is mounted in a casting, E, in the top of the frame or casement of the window. This casting consists of the recessed body 0, countersunk in a recess in the frame or casement, and the lateral ears 6, secured to the face of the frame or casement by means of screws or equivalent means.

F represents the clamp, which is aftixed to the front or inner side of the meeting-rail of the lower sash, and it consists of the bodyf, provided with the vertical tubular opening f, and a slot, f", in its front side communicating with the openingf; and G represents a camlever mounted in a recess, 1", which commu- 'nicates with the said opening, and the lever Serial No. 277,720. (No model.)

any time the clamp should he accidentally loosened the raised sash cannot reach the bottom of the easement before the stop strikes the bottom of the clamp. Further, this stop may be arranged in contact with the bottom of the clamp when the sashes are in their closed posit-ions, so as to obviate the necessity of using the clamp except when the cord is to be shortened to hold both sashes raised above the con ter of the easement. Thus the stop acts, in combination with thehollow body ofthe clamp, to provide convenient means for operating the sashes.

This balancing device, as will be seen, is simple, and with it the sashes may be arranged in any desired position. WVhen the cord is secured in the clamp, the lower sash may be moved either up or down and the upper sash will be moved in the opposite direction an equal distance; also, either sash may be moved while the other remains stationary. A curved spring, I, is arranged on the meeting-rail of the lower sash in such a position that when the sash is raised the spring will strike against the top of the easement and prevent a jar. The spring is affixed to the sash at its center by a staple or keeper, i, and it consists of the upwardlyconvex arms K K, extending on opposite sides of the staple or keeper. Similar springs may be arranged on the upper and lower edges of the upper sash; but only one is shown in the drawings, as this will illustrate the device.

I am aware that various devices of this character have been heretofore employed, and I do not wish to claim its features, broadly. The advantages of the improved clamp are, the cord may be inserted thereinto by passing it through the slotf in its face without drawing it longitudinally therethrough, thus saving time, saving trouble, and saving wear on the cord, for when the cord is to be adjusted to any considerable extent it maybe removed, drawn down to the desired point, and replaced.

Having described my invention, I claim- In asash-balance, the combination, with the upper and lower sashes, of the hollow clamp (low-frame, and extending through the openown I have hereto aflixed mysignature in presing in the clamp, and the adjustable stop seence of two witnesses. cured on the running portion of the cord near its free end and adapted to bear against the e 5 lower side of the clamp, substantially as speci- \Vitnesses:

fied. D. W. DAY,

In testimony that I claim the foregoing as my JOHN ALEN ROGERS.
